⇨ JapaneseThe figure of the Prototype Digimon of the “Doru Series” that achieved Ultimate-level by implementing “Death-X-Evolution” after experiments that aimed at even further evolution. Because self-activity depends on the Digicore of other Digimon, it is called a “Digicore Predator” and is nothing but a threat to other Digimon. By continuing to prey on other Digimon’s Digicore it remains active even though is dead and, because it contains in its body the information from massive Digicore, it can barely remain active as a single Digimon while covering its whole body in restrains.

Its Special Moves delete everything but the enemy’s Digicore, (Metal Impulse) and (Doru Djinn).

After it had ordered Magnamon of the Royal Knights to captures DORUgamon and bring him to it, Yggdrasill analyzed DORUgamon's data and created Death-X DORUgoramon from it. From there, Death-X DORUgoramon created hundreds of Digitama containing Death-X DORUguremon. It was later confronted by Alphamon and Omegamon when it was summoned by Yggdrasill. Although Omegamon barely hurt it, Alphamon easily destroyed it with a single attack. It was later revived by Yggdrasill as Death-X-mon to defend it.
